CONTINUOUSLY VARIABLE TRANSMISSION

摘要

Provided with first and second rotational members (10, 20), a sun roller (30), a plurality of planetary balls (40) sandwiched between the first and second rotational members (10, 20), a support shaft (41) of each of the planetary balls (40), a shaft (50), a carrier (60), an iris plate (80) and a worm gear (81) for tilting each of the planetary balls (40), and an input shaft (11) and an output shaft (21) individually fixed to the first and second rotational members (10, 20), respectively, in which a movable amount of the sun roller (30) relative to the carrier (60) in an axis line direction is set to be smaller than the movable amount of the second rotational member (20) relative to the carrier (60) in the axis line direction when the input shaft (11) is arranged so as to be relatively rotatable on an outer peripheral surface of the output shaft (21).
